Synthesis, Characterization, Optical, Electrochemical and Current-Voltage Characteristics of Coumarin Dyes.

A series of coumarin dyes having common acceptor and pi spacer with different donors were synthesized and characterized by spectroscopic techniques. The TiO nanoparticle has been synthesized by sol-gel method and characterized by X-ray diffraction, scanning electron microscopy and energy dispersive spectroscopy. Photophysical and electrochemical properties have been investigated.
